摘　　要：利用水热合成法制备了Keggin型结构的Ni-Mo-Zr杂多酸盐光催化剂,并利用红外光谱(IR)和X射线衍射(xRD)对催化剂进行了表征.实验以酸性绿B(AGB)为模拟污染物,考察了在紫外灯照射下,Ni-Mo-Zr杂多酸盐的投加量、AGB的初始浓度和pH值以及外加H2O2对光催化降解效果的影响.实验结果表明,当催化剂的投加量为0.8g/L时,pH为7时,初始浓度为10mg/L的AGB染料溶液,光照160min,脱色率可达92.64%.外加H2O2可以提高光催化反应效率.The photo catalyst of the heteropoly salt containing Ni-Mo-Zr with Keggin structrue was prepared with the hydrothermal synthesizes reactions and characterized by fourier transform infrared spectroscopy （FT-IR）. The influence of the amount of the photocatalyst, initial concentration of acidic green B（AGB） ,pH value of solution and H2O2 added were put to study by the degradation rate of AGB under UV light irradiation. The results of the experiments show that the concentration of AGB dye solution is 10mg/L, catalyst amount of Ni-Mo-Zr, 0.8 g/L ,and the pH 7, with UV irradiation 160min, the degradation rate of AGB up to 92.64%. In the system, H2O2 added can enhance the degradation rate of the AGB solution.
